(54) Supporting mechanism for pinch roller unit for use in magnetic recording/reproducing apparatus


(57) A supporting mechanism of the invention is for supporting a pinch roller for use in a magnetic recording/reproducing apparatus. A pinch roller (21) is rotatably mounted on a fixing shaft (50) that includes two separate parts, a supporting shaft (50b) and a hollow shaft (50a). The fine adjustment of the marginal movement height of the pinch roller (21) can be simplified in the thrust direction of the shafts. The shapes of the supporting shaft (50b) and the hollow shaft are simple to machine, and the smoothness of cylindrical surface can easily be achieved. The pinch roller (21) is held at a predetermined height with respect to a recording tape (6). The supporting shaft (50b) press-fittingly extends through the hollow shaft (50a). The hollow shaft (50a) is adjustably secured to the supporting shaft (50b) and is positioned in an axial direction of the supporting shaft (50b) so that the height of the pinch roller (21) is adjusted with respect to the recording tape (6).
